[Machine] The Prophet ﷺ used to frequently say, "Subhanak Allahumma wa bihamdik Allahumma ighfir li" (Glory be to You, O Allah, and praise be to You. O Allah, forgive me). But when the verse "When the help of Allah comes and the victory" [Surah An-Nasr, verse 1] was revealed, he said, "Subhanak Allahumma Allahumma ighfir li, innaka antal Wahhab" (Glory be to You, O Allah! O Allah, forgive me. You are the Generous Bestower). This is a valid chain of narration if Abu Ubaydah ibn Abdullah ibn Mas'ud heard it from his father and they did not omit it.
كَانَ النَّبِيُّ ﷺ يُكْثِرُ أَنْ يَقُولُ «سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ اللَّهُمَّ اغْفِرْ لِي» فَلَمَّا نَزَلَتْ {إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ} [النصر 1] قَالَ «سُبْحَانَكَ اللَّهُمَّ اللَّهُمَّ اغْفِرْ لِي إِنَّكَ أَنْتَ الْوَهَّابُ» هَذَا إِسْنَادٌ صَحِيحٌ إِنْ كَانَ أَبُو عُبَيْدَةَ بْنُ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ سَمِعَ مِنْ أَبِيهِ وَلَمْ يُخَرِّجَاهُ
